Dustin Aranda, 18, was charged Thursday with aggravated driving under the influence causing death, as well as possession of cannabis with intent to deliver, according to a Cook County Sheriff's Office release.

Police said Aranda was behind the wheel, with an 18-year-old female passenger, in a beige, 2002 Chevrolet Cavalier when it struck the Niles woman as she walked about 11:20 a.m. Jan. 17 in the 300 block of Greenwood Avenue in Cook County near Glenview.

Janina Kasperek, of the 8500 block of North Milwaukee Avenue, was found lying in a drainage ditch along the west shoulder of Greenwood Avenue, sheriff's office spokeswoman Sophia Ansari said.

Kasperek was pronounced dead just before noon the same day at Advocate Lutheran General Hospital in Park Ridge, according to the Cook County medical examiner's office.

Police found the Chevrolet in the drainage ditch on the east side of Greenwood, Ansari said.

Police said Aranda tested positive for THC, the principal psychoactive drug contained in marijuana, as well as benzodiazepine, a drug often prescribed to treat anxiety and insomnia.

Sheriff's investigators found 27 grams -- just shy of an ounce -- of marijuana in a sealed bag inside the car, according to police.

The passenger, Jocelyn Maldonado Verdin, of the 8300 block of North Odell Avenue in north suburban Niles, was also charged Thursday with possession of cannabis with intent to deliver, police said.

Both appeared in bond court at Skokie Branch Court Friday, police said, where bond was set at $270,000 for Aranda, who lives in the 8900 block of Kennedy Drive in unincorporated Cook County near northwest suburban Des Plaines. Verdin was released on a $20,000 personal recognizance bond and was ordered placed on electronic monitoring.
